WebContraction band lesions, a.k.a. myofibrillar degeneration, coagulative myocytolysis, kinetic cell death, and contraction band necrosis, can be regarded as accelerated necrosis of irreversibly injured myocytes. They represent hypercontraction with massive influx of calcium within injured myocytes which were still viable prior to reperfusion. WebThe firm mechanical connections are created between the adjacent cell membranes by proteins. The electrical connections (low resistance pathways, gap junctions) between the myocytes are via the channels …
